I can, therefore I am.
Be kind whenever possible. It is always possible.
Know or listen to those who know.
After a storm comes a calm.
Quality is not an act, it is a habit.
The most effective way to do it, is to do it.
Who seeks shall find.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
